[fthaksu]

Hi, i am trying some AT commands ESP8266 but it resets continously and finally stop working.

For example ;

Code: Select all

AT


OK
AT+CWMODE=1


OK
AT+CIPMODE=0


OK
AT+CIPMUX=1


OK
AT+CWJAP="..",".."

And it resets again and again, finally stop reseting but when it stop reset, I can't get any response from ESP8266 while turn off-on it. I have upgraded firmware from github files and I tried GPIO0 , GPIO2 is HIGH but still reseting. And I'm using arduino with ESP8266. It worked yesterday but today it is failing.. What can i do? Thanks.

Hi,

Code: Select all

2nd boot version : 1.1
  SPI Speed      : 40MHz
  SPI Mode       : QIO
  SPI Flash Size : 4Mbit


Sorry that the AT firmware is too large to fit in 4Mbit Flash, to run the AT firmware, you need 8Mbit or larger Flash.

So, what can i do exactly?

Hi,

Please download the AT firmware into Flash using ESP Flash Download Tool.

On the "DETECTED INFO" area of the ESP Flash Download Tool, it will show the actually flash size of your hardware module while downloading.

If your hardware flash size in only 4Mbit, sorry that you need to change to use another hardware module or change the flash on it.

If your hardware flash size is 8Mibt or larger, you need to select the corresponding flash size on the "Flash Size" area of the ESP Flash Download Tool to download bin files. You can download the AT firmware according to the documentation 4A-ESP8266__AT Instruction Set.

Thanks for your interest in ESP8266 !
